“…Several research studies have investigated the best path toward each targeted destination in downtown and urban areas . These studies mainly recommended that traveling vehicles avoid highly congested road segments; these studies also intended to find the best alternative path toward each targeted destination.…”

“…The second category in this field (i.e., distributed path recommendation protocols) produces more real‐time and more accurate traffic congestion avoidance recommendations. The path leading toward each destination is recommended through cooperative communication among a set of distributed processors (i.e., RSUs); these are scattered throughout the area of interest . Our previously proposed path recommendation protocol (ICOD) provides vehicles with accurate information concerning recommendations for the least congested path leading toward the respective destinations, in a dynamic and distributed manner.…”

“…No central data gathering function or central processor is required for distributed path recommendation protocols. At each road intersection, the next hop for each traffic flow is recommended according to the traffic characteristics of the surrounding road segments . A set of Road Side Units (RSUs) must be installed over the road network, and an RSU is installed at each road intersection to evaluate and to make recommendations to the surrounding traffic flow locally.…”

“…At each road intersection, the incoming traffic (i.e., input flow) is able to leave the intersection through three directions: straight, right, and left. The direction with the least amount of required travel time toward each destination is recommended for each traveling vehicle . Distributed path recommendation protocols handle scalability and accuracy issues, but they generate additional overhead in terms of bandwidth consumption over the communications network.…”

“…The details of Bal‐Traf and Abs‐Bal mechanisms are proposed in Section 5. Section 6 illustrates the performance evaluations of Bal‐Traf and Abs‐Bal mechanisms; these are compared with a typical distributed path recommendation protocol known as intelligent path recommendation protocol (ICOD) ; the purpose of this section is to illustrate the advantages and drawbacks of each mechanism in different scenarios. Finally, Section 7 concludes the paper.…”

In this paper, we propose both reactive and proactive balancing traffic path recommendation mechanisms, which we refer to as Bal-Traf and Abs-Bal, respectively. Bal-Traf is initiated when a certain output road segment located at any road intersection is detected in an overloaded situation. In the event that the existing traffic density of any output road exceeds its optimal capacity, Bal-Traf recommends that those vehicles that plan to pass over this road segment as next hop choose another, less congested output road segment. On the other hand, Abs-Bal is a proactive balancing traffic mechanism. Its main purpose is to distribute input traffic completely even among all output road segments at intersections. Moreover, Abs-Bal considers the best travel time of vehicles in addition to the goal of balancing traffic. From the experimental results, we can see that Bal-Traf eliminates the number of overwhelmed road segments over the road network in scenarios with only partial network congestion. It also decreases the number of congested road segments in scenarios with complete network congestion. However, it increases the density drastically over the remaining congested road segments in these scenarios. Abs-Bal performs well in decreasing the percentage of congested road segments and balancing traffic among road segments located throughout the road network, in the event of complete network congestion.

Targeting several destinations on the same trip is commonly seen over the downtown areas. Several drivers leave their home or work everyday targeting multiple end-destinations for shopping or entertaining purposes. The sequence of visiting destinations can be selected randomly by the drivers, especially if they are less familiar with the area of interest or with multi-destinations trips.However, expert drivers that travel more frequently towards several destinations should be more cautious planning their trips. They consider the relative locations of these end-destinations and use their historical knowledge regarding the traffic over the connected road segments there. This paper proposes an efficient multi-destinations trip planning protocol (MDPP) that recommends drivers with the best sequence of destinations to visit. The proposed protocol considers the location of each destination and the relative distance between all located destinations. It also considers the traffic distribution over the investigated areas of interest to recommend drivers to avoid highly congested road segments or road segments that suffer traffic issue such as accident or emergency existence. From the experimental results, we can see that the MDPP protocol has selected the best path towards the targeted destinations compared with other common selected sequences. It has decreased the travel time, fuel consumption, and the gas emissions for different investigated scenarios.
